On PsiOps Legend Cosmodrome after around the 12 minute mark or so, my weapons turned invisible, with no model present at all. This would be bad enough on its own, but those weapons would often not register shots at all. The ammo count would go down, but no sound could be heard when shooting, and no damage was dealt, without so much as a hitmarker. Enemies frequently teleport around for no apparent reason, but that pales in comparison to this. We couldn't even make it past the 2nd phase on the boss. Please look into this ASAP.
